The system allows you to create a payment order for converting your fiat currency into non-fiat currency within the system, and vice versa. It is possible to cancel a payment order if it was just created, as well as generate a request to cancel previously created payment orders. The client can always generate a statement of his accounts in the format set in the system for any period of time from the beginning of the account registration in the system. It is possible to manage the entire amount on the account if: - The account is not blocked; - The minimum balance has not been set; - There is no encumbrance on the account.
